Connector housing assembly and charging socket connector

Abstract

The present invention provides a connector housing assembly and a charging socket connector. The connector housing assembly has a housing configured to support a connection terminal; and a lock received in a chamber of the housing. The lock is movably installed in the housing and is adapted to be moved between a pre-locking position and a final locking position; the lock is provided with a blocking structure configured to lock the connection terminal when the lock is moved to the final locking position; the housing is provided with an operation port communicated with the chamber, and the lock is pushed to move between the pre-locking position and the final locking position by a tool inserted into the chamber through the operation port. Compared with the prior art, the assembly process of the connector housing assembly of the present invention is simple, and the productivity is effectively improved. A blind plug may be located in the operation port when the tool is removed from the port.

       6. The connector housing assembly according to  claim 1 ,
 wherein the housing comprises a housing seat and a cover covered on the housing seat, the chamber is surrounded by the housing seat and the cover, and the operation port is provided on the cover. 
 
     
     
       7. The connector housing assembly according to  claim 1 , further comprising:
 a lead frame on which a connection circuit is arranged, 
 wherein the lead frame and the lock are formed into a single integral piece by injection molding. 
 
     
     
       8. The connector housing assembly according to  claim 1 , further comprising:
 a blind plug adapted to be plugged into and seal the operation port, so as to ensure the air tightness of the chamber. 
 
     
     
       9. The connector housing assembly according to  claim 1 ,
 wherein the operation port of the housing is served as an air tightness test channel of the connector housing assembly. 
 
     
     
       10. A charging socket connector, comprising:
 the connector housing assembly according to  claim 1 ; and 
 a connection assembly comprising a connection terminal and a cable electrically connected to the connection terminal, 
 wherein the connection terminal is installed in the housing, and the cable extends out of the housing. 
 
     
     
       11. The charging socket connector according to  claim 10 ,
 wherein the operation part of the lock is aligned with the operation port of the housing along an axial direction of the connector housing assembly. 
 
     
     
       12. The charging socket connector according to  claim 10 ,
 wherein the operation part comprises a slot provided on the lock, and the tool is adapted to be inserted into the slot of the operation part. 
 
     
     
       13. The charging socket connector according to  claim 10 ,
 wherein the operation part comprises a protruding block formed on the lock, and the protruding block is adapted to match with the tool.
